Method for manufacturing system floor and floor base for system floor.

摘要

The present invention provides a floor panel (3) comprising a rectangular floor base (1) integrally forming each convex prop (13) in each corner portion and a concave portion (11b) on the upper surface of each prop, a height adjusting screw with a plate embedded in the concave portion of each prop, variably adjusting the height of the support position in a predetermined range between a lower position than the upper surface of the prop and a higher position than the upper surface of the prop, and a floor panel (3) supported by each prop of the floor base and having a through hole (30) of a jig adjusting the support position of said height of the adjusting parts in each corner according to the prop. In the method of manufacturing the floor base, convex portion (11a), which integrally projects to the upper surface side on four corners of of a skin (11), is formed, a concave portion (11b) is formed on the lower surface of said convex portion, concrete (12) is packed in the concave portion (11b), and a prop is formed to be integrated with said skin.
